In present embodiment, the mechanical hand 4 of this device is arranged on two-way leading screw 31, can be driven by spindle motor 3 and on
Lower movement.Also, because the characteristic of two-way leading screw 31, can start reversely to transport on moving to or after lower limiting point
It is dynamic, it is achieved thereby that up and down reciprocatingly shuttling movement.
In present embodiment, when mechanical hand 4 is moved from the bottom up, need first to limit module 12 and clamp nettle
11, second limits module 14 unclamps nettle 11, and main drum 1 stops operating, and such mechanical hand can be from tuning wheel(15)Place
Nettle is pulled back;When mechanical hand 4 is moved from top to bottom, then conversely, needing first to limit module 12 unclamps nettle 11,
Second limits module 14 clamps nettle 11, and main drum 1 starts to rotate take-up, and such main drum 1 can just retract on mechanical hand
The nettle for coming winds up.
In present embodiment, instantly conducting strip 441 is pressed on the first contact 72 and the second contact 72 ' so that the first contact
72 and second contact 72 ' circuit communication when, cylinder 43 is started working, drive gripping block 422 move, so as to coordinate limiting section
421 pairs of nettles are clamped.
In present embodiment, when upper conducting strip 451 is connected the 3rd contact 54 with the circuit of the 4th contact 54 ',
Then cylinder 43 drives gripping block 422 back to move, and unclamps nettle 11.
In present embodiment, this device clamps nettle 11 by arranging limiting section 421 and gripping block 422.In limiting section
421 lateral surface is provided with inclined plane 4211.When mechanical hand 4 is rotated with mounting disc, nettle 11 and the phase of limiting section 421
Contact, this inclined plane 4211 can produce the effect of guiding so that nettle 11 smoothly enters limiting section 421 and gripping block
Clamped position between 422.The inner concave 4212 of arc is then provided with the medial surface of limiting section 421, in gripping block 422 then
It is provided with prominent limited block 423;Limited block 423 is coordinated by inner concave 4212, can prevent nettle from departing from.
In present embodiment, the first restriction module 12 of this device can be mobile, so that nettle 11 can be equal
It is wound on evenly on main drum 1.The movement of the first cylinder 2 is driven by auxiliary-motor 72.The outfan of auxiliary-motor 72 is connected to secondary two-way
Leading screw, then matching pair feed screw nut, it is ensured that the first cylinder 2 can recover to original after extreme position is moved to
Position, iterative motion.First limit module 12 another effect be exactly after mechanical hand 4 moves to minimum point, by
During gradually rising, nettle 11 is clamped.
In present embodiment, when needing first to limit the realization clamping restriction effect of module 12, as long as to the first electromagnet
23 are powered, and the first electromagnet 23 attracts first permanent magnet 221 to move down so that the roller is pressed in institute after being powered
The upper end of the first cylinder 2 is stated, it is achieved thereby that clamping the effect of nettle 11.Specifically, exactly move to most in mechanical hand 4
When low spot begins to move up, now mechanical hand 4 causes lower conducting strip 441 to be pressed in the first contact 72 and the second contact 72 '
On so that the circuit communication of the first contact 72 and the second contact 72 ', now the electricity of the first permanent magnet 221 be turned on, with this
Meanwhile, the electricity of the second permanent magnet 621 is just disconnected.And disconnect the circuit of mair motor so that main drum 1 stops operating.
In present embodiment, second restriction module 14 effect one be after mechanical hand 4 moves to peak, gradually under
During drop, nettle 11 is clamped;Two is to adjust the direction from the nettle 11 of tuning wheel 15 so that mechanical hand 4 can be smooth
Crawl nettle 11.The second pressure-bearing spring 65, pointer 621 and rule 661 are provided with the second restriction module 14, in work
When can intuitively embody spring to be compressed the elastic force of generation be how many, be many so as to smoothly obtain the power on nettle 11
It is few.So arrange, nettle 1 can be avoided to be drawn bad, when pointer 621 points to soon the dangerous numerical value on rule 661, should
Stop drag nettle 11.
In present embodiment, when needing second to limit the realization clamping restriction effect of module 14, as long as to the second electromagnet
63 are powered, and the second electromagnet 63 attracts second permanent magnet 621 to move down so that the roller is pressed in institute after being powered
The upper end of the second cylinder 6 is stated, it is achieved thereby that clamping the effect of nettle 11.Specifically, exactly when mechanical hand 4 is moved to most
High point and when start to move down, now mechanical hand 4 causes upper conducting strip 451 to touch the 3rd contact 54 and the 4th
54 ' circuits of point are connected, and now electromagnet 63 is powered, and at the same time, the electricity of the first permanent magnet 221 is just disconnected.And start
The circuit of mair motor so that main drum 1 can rotate beginning take-up.
In present embodiment, the present invention can show and for nettle reclaim one section, then by main drum carry out last recovery again,
So as to protect winch, drive mechanism is especially protected, extend the service life of winch.
Protection scope of the present invention includes but is not limited to embodiment of above, and protection scope of the present invention is with claims
It is defined, any replacement being readily apparent that to those skilled in the art that this technology is made, deformation, improvement each fall within the present invention's
Protection domain.
